Osgood Ramp Exit, Resurfacing ramps: Summer-Fall 2017

Several I-15 construction projects will be completed in 2017. Work on I-15 will continue for several years.

Spencer to Montana

I-15 Spencer to Montana State Line Project

Work began in early August to resurface 15.3 miles of Interstate 15 between Spencer, Idaho, and the Montana state line in the summer of 2017. The project includes repaving ramps and cross-streets at the Stoddard Creek Interchange and Humphry Interchange (exits 184 and 190).

Traffic impacts:
• Crews will work in four-mile segments. I-15 will be reduced to one lane in each direction in the work zone.
• The speed limit will be reduced to 45 mph when crews are working and 65 mph when crews are not working.
• Because the pavement edge will be abrupt during paving, lane restrictions may continue during hours when crews are not working.
• On- and off-ramps may be closed at night (10 p.m. to 6 a.m.) at exits 184 and 190. Only one ramp will be closed at any time.
• Flaggers will direct traffic on local roads during paving at each interchange.

Along this project route the interstate road surface is deteriorating and needs to be replaced. The resurfacing work will eliminate rough sections and soft spots in the road. As a part of this project, ITD will also upgrade the guardrail on I-15. Through a method called Cold-in-Place Recycling, ITD will re-use the old pavement in the new roadway. This method reduces waste and lowers costs.

Fort Hall to Burns Rd

COMPLETE: I-15 Fort Hall to Burns Road Resurfacing

Approximately six miles of Interstate 15 from the Fort Hall Reservation boundary near Pocatello to Burns Road north of Fort Hall was resurfaced. Along with resurfacing, ITD upgraded the guardrail along I-15 and improved the clearance below the structures at the Railroad Overpass, Fort Hall Interchange and Sheepskin Road.

This fall, ITD will rehabilitate the Fort Hall Main Canal bridges once the canal is dry. All work is scheduled to be complete this fall.
